OK, I've read all the input and here is my final say:
I was the San Francisco Folk Art Museum where there was a show entitled "4 generations" of quilters. There was a wonderful video of the second generation who talked about her mother, her daughter and her granddaughter. She talked about picking up a piece of fabric (probably pretty much pre-cut by her to an unraggedy shape) and looking at it for a moment and then after a turn or two, began to sew.
The person doing the interview said, "But what if you make a mistake?" The grandmother's eyes flew open in astonishment (she doesn't make mistakes????) and she threw back her head and roared with laughter, and when under control she said, "Honey, if you make something with love there can't be any "mistake". Love doesn't leave room for mistakes." (my memory may be paraphrasing).
My answer to the question of my worst flaw: I still agonize about puckers, mismatching seams..... until I remember this wonderful woman and her beautiful way of relating to life.
